HINGE FOR FOLDING CHAIRS.

Application filed May 27, 1922, Seria1 No. 564,177. Renewed July 24, 1925.

To all whom it may concern:

vBe it known thatwe, ARTHUR F. Dnnsn, a citizen of the United States, and a resident of Union Course, in the county of Queens and State of New York, and VIL- nnmr B. lVILSHUsnN, a citizen of the Unitet States, and a resident of Mount Vernon, in the county of l/Vestchester and State of New York, have invented anew and useful Hinge for Folding Chairs, of which the following is a specification.

This invention relates to folding chairs of the character disclosed in application Serial No. 410,840 filed September 17 1920.

In that application a two-part seat of relatively rigid material is pivoted to pivotally connected legs and the center pivot connecting the two parts of the seat together consists of a wire bent into three lengths, one, a long length, and the other, two short lengths that are coaxial witheach other and parallel to the long length. When subjected to stresses the wire is apt to become distorted.

The main object and feature of this invention is to provide a hinge for the central part of the seat that will adequately resist stresses to which it may be subjected.

In the accompanying drawings the invention is embodied in one preferred and concrete form in which Fig. 1 is a perspective view of a chair embodying the invention.

Fig. 2 is a detail View of the central hinge portion of the chair.

Fig. 3 is a detail view of the hinge.

1 indicates the legs pivotally connected together in the manner described in the application referred to and also pivotally connected, at 2, to the two-part seat 3 and l.

5 indicates the central hinge connecting he two parts of the seat and consists, as shown, of a wire bent into two sets of parallel lengths, the sets being arranged end to end. One set is indicated by the lengths 6 and and the other by the lengths 8 and 9. 1t Wlll be observed that the lengths of each set are connected together as at 10 and also that each length of each set is connected by a cross-over portion 11 to that length of the other set that is not coaxial therewith. In this'way the lengths which are connected together by the cross-over portions receive stresses that act in opposite directions and therefore tend to neutralize each other by reason of said cross-over portion. The free ends 12 of the Wire may be located in one of the lengths and, if desired, these free ends may be welded or otherwise fastened together.

We claim:

A hinge consisting of a wire bent into two sets of parallel lengths, said sets being arranged end to end and thelength of each set being connected together, each length of each set being connected by a cross-over. portion to that length of the other set that is not co-axial therewith.

Signed at Brooklyn, in the county of Kings, and State of New York, this 17th day of May, 1922.
